The correct answer is "active transport is ATP dependent whereas in passive transport molecules use kinetic energy to move across the membrane." in active transport cells use molecules embedded on the cell membrane called carriers in the presence of energy. cells use energy and carriers because molecules must move against concentrated gradient inside the cell. on the hand, passive transport is a process by which molecules move from the region of high concentration to the region of low concentration across plasma membrane until balance is obtained on both sides of the membrane. once equilibrium has been achieved in passive transport the movement of molecules stops.

<em>Substitution is a type of mutation where one base pair is replaced by a different base pair. The term also refers to the replacement of one amino acid in a protein with a different amino acid.</em>

The remaining ratio of alleles is about 3:1
<h3>What about alleles?</h3>
- The term "allele" is employed to refer to a gene's alternate form or variants.
- For each autosomal gene, one allele is inherited from each parent, and that we often group the alleles into groups.
- Usually, we ask them as normal, wild-type, aberrant, or mutant alleles.
- For instance, a dominant allele can overcome the characteristics of other recessive alleles;
- These features are what determine an individual's eye and hair color, for instance .
- In this instance, the dominant brown eye alleles outnumber the recessive blue eye alleles.
- Any of two or more genes that may alternately appear at a certain location (locus) on a chromosome is referred to as an allele, also referred to as an allelomorph.
- Alleles may exist in pairs or there could also be many alleles influencing how a certain trait is expressed (phenotype).
- Each gene during a human has two copies (or alleles), one from each parent.
- Alleles significantly contribute to the event of each person's unique traits.
- Alleles are variants of the identical gene with a minor difference in the DNA base sequence.
- An allele may be a gene's variable form.
- Some genes exist during a number of forms, all of which share the identical genetic locus on a chromosome.
- Because each genetic locus in humans has two alleles—one acquired from each parent—they are referred to as diploid creatures.

Answer:
Option C.
Ocean acidification is the main ecological problem due to mariculture.
Explanation:
- Mariculture also known as the aquaculture that stands for the fish farming occupation.
- The main ecological problem that mariclture addresses is the environmental degradation especially the water pollution.
- Many studies suggests that the tradition of mariculture has been increasing the acidificaton in ocean water that is directly affecting the marine organisms and plants.
- A build up of organic material beneath fish farms impacts the flora and fauna of an area.
- That makes drastic changes on sediment chemistry.
